Answer 2

To solve the equation −|x| + 12.75 = -3, you can follow these steps:

1. Add 3 to both sides of the equation to isolate the absolute value term: -|x| + 12.75 + 3 = -3 + 3

This simplifies to:

-|x| + 15.75 = 0

2. Now, you want to isolate the absolute value term, so multiply the entire equation by -1 to change the sign of both sides:

-1 * (-|x| + 15.75) = -1 * 0

This simplifies to:

|x| - 15.75 = 0

3. Finally, to isolate the absolute value of x, remove the negative sign by taking the absolute value of both sides:

|x| = 15.75

Now, you have the absolute value of x equal to 15.75. To find the solutions for x, you need to consider two cases:

Case 1: x is positive: x = 15.75

Case 2: x is negative: x = -15.75

So, the solutions to the equation −|x| + 12.75 = -3 are x = 15.75 and x = -15.75.
